This disc-shaped filter is a multi-layer water treatment cartridge for pet water dispensers and smart circulating fountains, designed to reduce TDS while removing chlorine, odours and visible debris. It combines high-density PET nonwoven, ion-exchange resin and coconut-shell activated carbon in a layered build that balances filtration efficiency, airflow resistance and service life. Ranveth supplies it as a standard disc or as an OEM/ODM build to match your dispenser model.
The performance of this filter comes from how its three media are paired rather than from any single material. The outer high-density PET nonwoven acts as a mechanical pre-filter, catching hair, dust and floating particles before they reach the inner layers. This protects the resin and carbon downstream and helps keep resistance low across the life of the cartridge.
The middle layer is a high-efficiency ion-exchange resin, selected to soften hard water by exchanging calcium and magnesium ions and to reduce certain heavy metals, which is the basis of the TDS-reduction effect. The inner layer is premium coconut-shell activated carbon, chosen for its pore structure and its ability to adsorb residual chlorine, odours and taste-causing compounds. Together the layers deliver three functions: interception of debris, ion exchange for softening, and adsorption for chlorine and odour control.
For a buyer, the practical consequence is that the media pairing drives three outcomes at once. Efficiency depends on the resin grade and carbon activity; airflow and water flow resistance depend on the nonwoven density and the compaction of the media bed; service life depends on how well the pre-filter protects the resin and carbon from fouling. Ranveth can adjust the resin-to-carbon ratio and the nonwoven specification to shift the balance toward longer life, lower resistance or higher TDS reduction, depending on your market and dispenser design.

This cartridge is used in automatic cat and dog water dispensers, smart thermostatic circulating pet fountains and other pet water purification equipment. It is a fit for brands and distributors serving pet owners who want softer, cleaner-tasting water for their animals without changing the dispenser itself. The disc format suits flat filter seats in these appliances, and the standard build is compatible with common dispenser models; custom dimensions and connection details can be developed for specific models.
Because the filter addresses hardness, chlorine and debris together, it is also relevant to markets where tap water is hard or heavily chlorinated. In those conditions the resin and carbon work harder, which is why the replacement interval is stated as a range rather than a fixed figure.
To quote a custom disc filter accurately, we need the following from you:
With these details we can propose a media ratio and nonwoven specification, then confirm samples and pricing. If you are still defining the product, our team can work from a dispenser sample or a sketch and recommend a build that fits your target performance and cost.
Ranveth's media choices are test-backed: our in-house laboratory holds CNAS accreditation and can issue test reports on filtration efficiency, dust holding capacity and resistance, so the resin and carbon pairing in this filter can be verified against your requirements rather than assumed.
Production runs in a 50,000 m² plant that includes six cleanrooms totalling 20,000 m², which supports stable, contamination-controlled output for water-contact products. The factory holds IATF 16949 (achieved in 2024) and ISO 9001, ISO 14001 and ISO 45001 system certifications. Products comply with REACH and RoHS environmental regulations, and compliance documents can be provided. With more than 20 years of filtration R&D and manufacturing experience and over 1,000 filtration solutions developed, we support OEM/ODM customisation of dimensions, structure, filter media grades, frame material, logo and packaging. Quality control covers IQC, IPQC and OQC through the process, and multiple automated lines support monthly capacity in the millions of pieces. Our address is Zhongshan, Guangdong, China.
To evaluate this disc filter for your dispenser line, send us your device or vehicle model, size or drawing, required airflow or water flow, operating conditions, quantity and any branding needs. We will respond with a recommended build, sample timing and a quotation. Contact Ranveth to start the conversation.
It uses a layered build of high-density PET nonwoven, high-efficiency ion-exchange resin and premium coconut-shell activated carbon. The nonwoven intercepts debris, the resin softens water and reduces TDS, and the carbon adsorbs chlorine and odours. The ratio of these media can be adjusted for different performance targets.
The outer nonwoven protects the resin and carbon from fouling, which helps maintain flow and extend usable life. Efficiency depends mainly on resin grade and carbon activity, while resistance depends on nonwoven density and media compaction. Ranveth can tune these variables to balance TDS reduction, flow and replacement interval for your market.
Yes. We support OEM/ODM customisation of dimensions, structure, filter material ratio, logo and packaging. Send us the dispenser model or a size drawing and we can develop a disc that fits the filter seat. Custom samples are typically developed within 2–4 weeks.
Standard specifications typically start at 5,000–10,000 pieces, while custom OEM orders generally start at 10,000 pieces depending on complexity. Standard lead time is about 15–25 days, and custom orders including tooling take about 30–45 days. Monthly capacity is in the millions of pieces.
The suggested replacement interval is 2–4 weeks, depending on local water hardness, pet drinking frequency and the number of animals. In hard or heavily chlorinated water, the resin and carbon work harder, so the shorter end of the range is more appropriate. We can adjust the media ratio to optimise life for your market.
Yes. Standard samples usually ship within 3–5 working days, and custom samples within 2–4 weeks depending on complexity. Each sample set can include technical parameters, material details and CNAS laboratory test reports to support your evaluation.
Our CNAS-accredited laboratory can issue reports on filtration efficiency, dust holding capacity and resistance. For water filters, we can also test TDS reduction and flow performance. These reports help you verify the media pairing against your specification.
Send us your device model, size or drawing, required water flow, operating conditions and order quantity. We will recommend a media build and provide a quotation. <a href="/en/contact">Contact Ranveth</a> to begin.
